"Tucker’s wheelchair was life-changing for him and us. He was so happy that he could keep up with his brother and sisters again," Herman said.

Tucker passed away earlier this year, but his family said the joy and love he brought to their lives will live forever.

Contest organizers said entries came from 27 different countries and 35 U.S. states. Dogs like Tucker weren't the only ones modeling their mobility devices; goats, cats, a duck and even a chicken participated.
